We experience issues when using the implicit OAuth flow in a WP7 Mango browser control and trying to login with openid. The login process itself works fine (althought the css of the openid page does not get loaded). But the redirection to stack exchange and the app does not work as expected.

I can't reproduce the implicit flow failing on my device, can you duplicate it from a known IP and give me the IP and start/end times involved so I can check our traffic logs?
